Application September 9, 1948, Serial No. 48,467

.opening therein.

An important object of the invention is to provide an oil burner including a combustion chamber which may be easily and quickly attached to the outside of a furnace without neces- 'sitating any changes or alterations in the con-- struction thereof.

Afstill further object is to provide an oil burner of asimple and practical construction, which is efiicient and reliable in its operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view;

Figure 2 is a longitudinal sectional view taken on a line 2-2 of Figure 1;

Figure 3 is a transverse sectional view taken on a line 33 of Figure 4; and

Figure 4 is a longitudinal sectional view taken on a line 4-4 of Figure 3.

Referring now to the drawing in detail wherein for-the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a hollow substantially cylindrical body which forms a combustion chamber formed at one end with an attaching flange 5 for attaching in a horizontal position to the outside of a furnace, at the fire door or other opening.

A neck 1 is formed at the end of the body 5 adjacent the flange 6 and which comprises the outlet end of the combustion chamber and a nozzle 8 is secured in the neck by screws or the like 9. The nozzle is formed with a tapered opening Ill.

The opposite or rear end of the body 5 is formed with an air inlet opening II and an air deflecting or dividing disc I2 is positioned in the body 5 in the path of the air entering the opening I I and cast or united with the body by means of webs l3 to support the disc [2 transversely in the body and with its side edges spaced from the wall of the combustion chamber. The disc 2 His also formed with ;a central air passage H. A pair of upper bafiies i=5 are .cast with-the top of the body 5 between whichis a tapped :opening it for attaching anrignition plug to :the body.

A pair of lower baiiies ll and it are castgin the lower portion of ibody "5 immediately beneath the upper bafiles l5 and between :which'is :positioned a tapped opening 1:9;for attaching an oil supply-line thereto.

A vaporizing plate 20 is secured in the body 5 by means of a screw 2| with the front end of the plate resting on the lower bafile l8 and with its opposite'or rear end of the plate overlying the oil inlet port I9.

,The rear end of plate 20 is bifurcated to form a pair of spaced parallel arms 22 which are bent upon themselves to clamp the ends of a wicking strip 23 of non-combustible material which is curved downwardly at its center to absorb excess oil when the burner is cold.

An opening 24 is formed in rear lower baffle ll, to permit oil to spread over a larger area in the body 5, when the burner is cold.

In the operation of the burner, a suitable blower (not shown) is attached to air inlet H to force air through the burner. The wick 23 is initially ignited by a plug (not shown) attached in opening 16 and the flame passing over plate 20 will heat the plate andvaporize oil collected under the plate. The resultant flame is projected from nozzle 8 into the furnace.

The heating of plate 20 by the flame will cause vaporization of the fuel to produce an efficient combustion.

A plug 25 is threaded in the top of body v5 to permit use of'a screw driver for tightening screw 2| to hold vaporizing plate 20 in afixed position.

Having described the invention, what is claimed as new is:

1. An oil burner comprising hollow body forming a combustion chamber having an air inlet at one end and an outlet at its opposite end, a nozzle in the outlet, an oil supply port in the bottom of the body, a vaporizer supported in the body above the oil supply port, a starting wick carried by the vaporizer. and an air deflector in the body between the inlet and the vaporizer and obstructing direct passage of air through the body.

2. An oil burner comprising a hollow body forming a combustion chamber having an air inlet at one end and an outlet at its opposite end, a nozz e in the outlet, an oil supply port in the bottom of the body. a vaporizer supported in the body above the oil supply port, and an air deflector in the body between the inlet and the vaporizer and obstructing direct passage of air through the body, said vaporizer comprising a horizontal plate and a starting wick carried at the front end of the plate.

3. An oil burner comprising a hollow body forming a combustion chamber having an air inlet at one end and an outlet at the opposite end, a nozzle in the outlet, an oil supply port in the bottom of the body, an elongated vaporizer supported in the body above the oil supply port, a starting wick at the front portion of the vaporizer and an air deflector in the body between the inlet and the vaporizer and comprising a disk supported in the body opposed to air entering the body and having its edges spaced from the walls of the combustion chamber to obstruct direct passage of air through the body.

4. An oil burner comprising a hollow body forming a combustion chamber having an air inlet at one end and an outlet at its opposite end, a nozzle in the outlet, an oil supply port in the bottom of the body, an air deflector positioned in the combustion chamber immediately rearwardly of the air inlet and in the path of air entering the inlet, an igniter receiving opening in the top of the body, a pair of upper baffies in the body between which the igniter opening is positioned to pocket 011 vapor between the bafiles to facilitate starting of the burner, a pair of lower bafiles in the body between which the oil supply port is positioned to pocket oil between the lower bafiles, a vaporizer plate supported in a horizontal position over the oil supply port and resting on'at least one of said lower baflles, and a starting wick at the front portion of said vaporizer plate.
